crossorigin
The crossorigin attribute is an HTML attribute used on elements like script, link, and img when they load a resource from a different domain. It signals to the browser to make a CORS request, which is necessary for securely accessing certain cross-origin resources and for enabling detailed error reporting from third-party scripts.
